upward therefrom;y Secured by screws to theunder sideiof the base 17 is a base plate Q0`covered with a pliable material 21, such` as cloth, to prevent the copy holder from 00 marring or scratching the polished surface of a desk onfwhich it is supported.

Aj displaceable back plate 22 is slidably mounted in grooves in the rear longitudinal edgcsol' the side flanges `1-1 and lfrom 65 the bottom of the copy holderand/the closing moyem'ent of said` baclr is limited by the top shelf 16. The lbottom plate QOis securedv to the base 17 after the back plate y22 is closed andholds the sameinposition.k

4To illustrate the invention in working relationgto a typewriter,r there is diagrammatieally illustrated in Fig. 1 such. a machine indicated as an entirety by the charactercA with .theexception of its rear legs 'T5 P and rear frame barl CL To permit the copy holder, to be placed in a plde'termined ,position back ofthe typewriter the base 17 and its side flanges 1,8 are so designe-d asA to project underthe rear legs B an underthe rear `iframe bar CL To releasablyk secure the copy holder'in this position in respect tothe typwriter A thel saine is provided with a pair offor'wardly projecting spring arms 23 havinghook-like free ends 241` .arranged to' yyieldingly engage thfefunde'r .side ofthe rea'r framebar GL These Aarms 23am formed by tangentially extending lthe outer ends of afpair of axiallyalig-ned coiledA springs 25 through which a rock shaft Q6 axially extends. The end portions' ofthev shaft 26 are journaled in the side flangesv 1L1v and` 15, extend outward thereof, and' their projecting ends are sea suitable tool i`or operating said shalt, as will presently appear. `The inner ends of the springs 25 are tangentially extended, asv indicatedat i127, and engage the back of the body 13 asa base of resistance, as best. shown in F 6. The 'spring arms 23 extend throughiverticalelongated slotsy 28 in the bodylS A pair of hook-like lugs 29Hare securedtov the-rock shaft 26 andoverlie the spring arms 2'3 for vsimultaneously pressing the same when the rock shaft 26 is moved in a predetermined direction. y ,.Obviously, by simultaneously pressing the springia-rms Q3' thesame may be freely inserted under .the rearframe barv C andthen released to secure the copy holder thereto. A like move'n'ien't 'of the spring arms Q3 will also release the saine from the typewriter. For holding a copy sheet, not shown, against the front face of the body 13 there is pro vided a yieldingly held clamping bar 3() having at the intermediate portion of its upper edge a rearwardly extended spring hinge 31 that extends through a slot 32 in the body 13 and attached to bearing ears 33 on the back of the body.

On the end portions of'the clamping bar 3() are rubber bands 34 that are provided to increase the frictional engagement between said clamping bar and a copy sheet. Said clamping bar is arranged to engage the top i portion of a copy sheet and hold` the same pressed against the front face of the body 13. The front lower edge portion of the clamping bar 30 is outnf'ardly bulged to afford a linger hold by which said bar may be raised and the body 13, at the slot 32, is notched at 36 to afford free access to said finger hold.

To held a note book, not shown, there is provided a horizontal retaining bar 37, the end portions of which are rearwardly offset and secured to the front face of the body 13 above the clamping bar 30. The retaining bar 37 is adapted to hold a note book at its bound edge by having one of the covers thereof inserted between the body 13 and said bar, from the top thereof. cover of the book and its leaves as they are turned over the shelf 16 are held by a weight 38. This weight 38 is carried by the arm 39 that normally extends parallel over the shelf 16 and is hinged thereto at 40 for vertical swinging movement.

The line guide and spacer yincludes a channeled slide 41 mounted for vertical sliding movement on the side flange 14 with one of its` flanges having sliding contact with the front face of the body 13 and its other flange extends into a long` vertical notch 42 formed in the rear edge portion of said flange 14 and has sfsliding engagement with the rear end of said flange in the notch 42. Formed with the rear flange of the slide 41 an inwardly extended pressure finger 43 arranged to engage the back of the body 13 for vertical sliding movement `thereon and hold said slide against transverse annular movement on the flange 14 by an outward pull on the outer flange of the slide 41. The slide 41 is yieldingly and frictionally held against the flange 14, where set, by a shoe 44 in the form of a U-shaped spring, one varm of which is secured to an angle bracket 45 on said slide, and its other or free arm is arranged to slide on the inner face of the side flange 14. The angle bracket' 45 is secured to the rear side flange of the slide 41 by having one of its members inserted through a slot 46 and secured 'to said flange by a screw 47.

` One end of a horizontal main straight edge bar 48 is secured to a relatively long The other bar() has one of its ends pivoted to the free end of the `main straight edge bar 48 for vertical swinging movement parallel therel to. W'hen the supplemental straight edge bar 50 is adjusted to form an extension of the main straight edge bar 48 the same is supported on a stop lug 51 on said straight edge bar 48. A hook-like lug 52 on the lug 49 is provided to support the free end of a supplemental straight edge bar 50 when folded as shown in Fig. 2. I

The following connections are provided for lowering the slide 41 step by step to intermittently move the straight edge bars 48 and 56 from line to line over the face of a copy sheet or the leaf of a note book on the copy holder, to wit:

A gravity held dog 53 is pivoted at 54 to the rear side flange of the slide 41 for cooperation with a ratchet bar 55 mounted for vertical endwise movement in upper and lower bearing brackets 56 on the inner face of the side flange 14. This ratchet bar 55 is provided with a multiplicity of longitudi nally spaced holes in any one of which the dog 53 will lenter and interlock therewith during a downward movement of the ratchet bar 55 and secure the slide 41 to said bar for common movement therewith. During an upward movement of the ratchet bar 55 the ,dog 53 will move over said bar with a ratchetlike action, thus permitting the slide to remain stationary and be heldV by the shoe 44.

To manually release the dog 53 from intei-locking engagement with the ratchet bar and thus permit the slide 41 to be moved vertically to either raise or lower the straight edge bars 48 and 50, the same is provided with a finger' piece equipped lever 57. The lower end of the ratchet bar 55 is connected to one of the arms` of a bell crank 58 by a link 59. The bell crank 58 is pivoted to a bearing lug 66 extending forward from the face of the body 13 and the arm of said bell crank to which the link 59 is attached extends rearward through a. vertical slot 61 in said body. The other arm of the bell crank 58 is attached to a rock shaft 62 by a crank-actuating arm 63 on said shaft. Said i ings 64 and are made square in cross section l for the application of a lever 65 for operating the same.

This lever 65 l extends horizontally forward from the rock shaft 62 and has on its rear end a long socketsleeve 66 adapted to be telescoped onto either of the projecting ends of the rock shaft 62 and interlocked therewith for common` rocking movement. A coiled spring 67 is attached to the bell crank 58 at its connection with the link 59 and anchored tothe back of the body 13 above said bell crank. This coiled spring is under strain to normally hold the ratchet bar raised through the link connection 59 and the free or outer end of the lever 65 raised through the bell crank 58 and crank arm 63 acting on the shaft 62.

To cause the slide 4l to move predetermined steps of downward movement and thereby selectively set the straight edge bars .t8 and 50 for single, double or triple spacing, the l-ever 65 is provided with an adjustable stop 68, in the form of an upright stem, the lower end of which is arranged to engage the table top I) as a base of resistance, as indicated by a single line in Fig. l, and on which the typewriter Aand copy holder are supported. This stop v 68 is mounted in a bore-like seat in the outer end portion of the lever 65 and has on its upper end a rubber capped finger piece 69 by which the operator may depress the stop 68 to operate the lever 65. This stop 68 is held in its seat for longitudinal adjustmentin the lever 65 for different line spacing by a U- shaped latch 7 0 that embraces said lever and has on its side members edgewise spaced ears 71 pivoted at 72 to said lever. The stop 68 extends through alined holes 7 3 in the side members of the latch and is provided with upper, intermediate and lower' pairs of circumferentially extended grooves 74, 75 and 76, respectively, into any one pair of which the sid-e members of the latch 70 may be inserted to releasably lock said latch to the lever 65. A coiled spring 77, anchored to the lever 65, engages the intermediate portion of the latch 7 0 and yieldingly holds the same interlocked with the stop 68. 'Io release the latch from the stop 68 it is only necessary to press the intermediate portion of the latch inward against the tension of the spring 77. locked with the grooves 74 or 7 5 or 76, said stop is positioned to cause the straight edge bars 48 and 5() to move steps of movement for single, double or triple spacing, respectively.

For variable or irregularspacing the stop 68 may be adjusted for trip spacing and the' operator, bv manipulating the lever 65 by slight touches can work the straight edge bars 48 and 50 down to the desired position. It .is therefore evident that this device is capable of use for positive or for variable spacing. j

Obviously, in line feeding movement less than that for which the stop 6.8 is set, the

IJVhenthe latch 70 is interoperationv may be produced simply by pressing the lever 65 down a distance less than that required to bring the stop into action. When it is desirable to move the spring arms 23 into operative positions to release the same from the typewriter or apply the same thereto, the lever 65 may be detached from therock shaft 62 and applied to either end of the rock shaft 26 to operate the same.

What we claim is:

l. In a holder of the kind described, the combination with a body and means for supporting the same', of a travelling member mounted on the body, a straight edge bar carried by said men'iber, means including an operating lever for imparting steps of movementto said member, a stop mounted on the lever for relative adjustment and arranged to engage an abutment to limit ther movement of thelever, and a latch for holding the stop in predetermined different adjustments in respect to the lever to cause said steps of movement to be of a selective predetermined length and the movement of the straight edge vbar to be of a predetermined difl'erent line spacing.

2. The structure defined in claim l in which-said stop is in the form of an upright stem having at its top a finger piece by which the lever may be operated and 1on-y gitudinally spaced lock notches for the latch.
